Why Your Generator Might Fail After an Earthquake or Flood
We received a call today from a homeowner in California with a pressing question: “Why did my generator not work after the earthquake?”
Not surprisingly, it was a natural gas generator. After the earthquake, the power was cut off, and his generator failed to operate.
It turns out he had a seismic natural gas shut-off valve installed. These valves are designed to detect significant ground movement, such as during an earthquake, and immediately shut off the gas supply to prevent potential leaks and explosions.
When this happens, pressure-testing is required by law before the gas company can restore gas service. This process can take days, weeks, or even months, causing significant inconvenience and potentially leaving homeowners without power for an extended period. Understandably, the homeowner was not happy at all.
And it’s only going to get worse.
California is investing over $16 million to install thousands of quake-detecting sensors statewide. These sensors provide utilities with precious seconds to shut down before the shaking starts. While this is a critical safety measure, it also means there is no telling how long it will take the utility company to test for leaks and restore the fuel supply next time.
It’s important to note that during flooding, utility companies often shut off gas supplies to affected areas to prevent gas leaks and explosions. Homeowners are advised to know the location of their gas shutoff valve and turn off the gas if they anticipate flooding in their area. After an earthquake or flood, it is crucial to check for gas leaks. If a leak is suspected, evacuate immediately and contact the gas company or emergency services.
Having automatic shutoff valves and knowing how to shut off the gas supply manually are essential safety measures in areas prone to natural disasters.
Natural gas powers over 35% of the power generating stations nationwide.
This reliance on natural gas underscores the importance of understanding and preparing for potential interruptions in gas supply due to seismic or flood events.
For homeowners relying on natural gas generators, consider the potential impacts of these safety systems and plan accordingly. Ensuring backup power reliability might involve exploring alternative fuel options or ensuring that you have a clear and quick way to restore your gas service after a shutoff event.
This updated post provides comprehensive information on the importance and impact of gas shutoff procedures during earthquakes and flooding, helping homeowners understand the critical safety measures in place and their potential effects on power reliability.
